I need help with PhysioEx 9.0 Exercise 8 Activity 3

Will someone please help me answer the following questions?

1. Describe the effect that boiling had on pepsin and how you could tell that it had that effect.
2. Was your prediction correct aboutthe optimal pH for pepsin activity? Discuss the physiological correlation behind your results.
3. What do you think would happen if you reduced the incubation time to 30 minutes for tube 5?

Boiling inactivated the pepsin. This is evidenced by the fact that no activity was seen with Tube #1. However, the enzyme was very active in Tube #2.

The correct prediction is pH 2.0. This is because pepsin is most active at the pH of gastric juice which is about pH 2.0.

Follow forum rules, two questions per thread.
